Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed April 12, 1910. Serial No. 555,107.

To all whom it may concern.'

Be it known that l, BENJAMIN S. MQCLEL- LAN, a citizen of the UnitedStates, and residing at Chicago, in the county of Cook and State ofillinois, have invented a new and useful Improvement rin Y Window-Sash,of which the following is a complete specifica` tion.

Car window sash as heretofore constructed have had their lower innercorners or edges subjected to considerable injury by being jammed orsplintered by careless employees while passing car seats or other`articles out of the open window. Furthermore where the bottom weatherstrip for the sash protrudes beyond the outer edge of the sash itbecomes injured by the window washers passing their brushes or othercleaning devices across it, and thefeiliciency of the strip is therebysoon destroyed. And, also,'where the strip protrudes outwardly fromAbeneath the bottom of the sash, water will pass by it and enter beneaththe sash by reason of its capillary attraction.

The main objects of this invention are to provide a window sash having ametal reinforced lower edge adapted to protect it from injury; toprovide a window sash having its bottom rail provided with a detachableprotecting bar or member on its inner lower' edge which is adapted toprotect the edge of the rail from injury, and is also adapted to bereplaced by another in case it becomes injured: and to provide a windowsash having a bottom weather strip, the outer edge of which `terminatesinwardly from the outer face of the sash, so that the outer edge of thesash will provide a water drip and prevent the water from creepingbeneath the sash.

A specific construction embodying the invention is illustrated in theaccompanying drawings, in which:

Figure l is a fragmentary, vertical section of a window having a sashembodied in this invention. Fig. 2 is a fragmentary view of the windowshowing parts in horizontal section and parts in plan view.

In the construction shown, the window sill l is inclined downwardly onits upper surface in the usual manner to provide a seat for the sash Q,which is also inclined downwardly and outwardly on its lower edge toconform to the sill.

The bottom of the sash is provided on its lowerl inner corner with ametal-reinforcing or protecting bar 3, which extends the full length ofthe bottoni rail, and has its edge or back 4 flush with and lying in theplane of the inner face of the sash. The bottom 5 of said bar isinclined to correspond to the in! clination of the sill and to seatflatly thereon when the sash is in closed position. The bar 3 isattached to the sash by means of screws 6 evtending therethrough andinto the sash ral Preferably, and as shown, the protecting bar 3 isformed of a channel bar, the width of which is approximately one halfthe thickness of the sash rail, and the channel of which opens towardthe outer side of the sash. The bar is preferably seated in a rabbetyprovided in the bottom of the sash so that the lower outer edge 7 ofthe sash extends slightly `below the upper iiange of the channel andpartially closes the opening in the bar.'

Carried in the channel is a flexible weather strip 8 of rubber or othersuitable material, which extends the full length of the channel land issecured therein by meansV of the screws 6 passing therethrough. The freeedge 9 of the strip projects forwardly from the channel and lies beneathand in close contact with the depending edge 7 of the sash, butterminates inwardly of the outer face of the sash, so that water runningdown said outer face will drop ofil onto the sill without touching thestrip. The strip 8 '1s of greater thickness than the distance betweenthe portion or edge 7 of the sash and the top of the sill when the sashis at the lower limit of its movement, so that the sash when closed willslightly compress the strip between the edge 7 of the sash and the sill,as shown more clearly in Fig. 1.

The protecting or reinforcing bar 3 prevents the lower inner edge of thesash from becoming injured by articles hitting the sash and thereforepreserves a neat iinish for the bottom of the sash. The bar also affordsa means for retaining the weather strip in place, and owing to the factthat the bar is seated in the rabbet in the sash it will withstand anyordinary blow without becoming loosened or damaged.

Inasmuch as the weather strip does not protrude forwardly from beneaththe sash, it cannot be injured when washing the windows. and it alsopermits the water to drop directly from the sash to the sill.

While I have shown but one specific emnation with the lower sash rail, asheet metal channel member having a vertical back or web and upper andlower parallel flanges,

said channel member being applied to thew bottom face of said rail withits channel opening outwardbelow the same and toward the outer verticalface of said rail, said webv or back extending below the bottom faceofsaid'rail from the inner vertical face thereof, said upper flangebearingv against the bottom face of said rail and said lower flangeextending beneath and spaced vertically below the bottom face of saidrail, a iflexible flat weather-strip below the bottom face of said railand' having'its inner mar ginalportion insertedin the channel ofy saidchannel member; the remaining portion of said strip projecting outwardyfrom said flanges and beneath the bottom faceof said railand terminatingshort ofA the outer edge of the same; alll portions of said weatherstripbeing entirely below the bottom face of said rail; and saidweather-strip and lower flange seating on the sill when: the

sash is closedA and forming` the supportfor said sash, andfastening..members` inserted through said flanges and the portionL ofthe weather-strip therebetween, for securingV said channel member andweather-strip to said rail. v

2. Awindow sash, comprising in combination with the lower sash rail, asheet metal member embracing a vertical back or web and a laterallyprojecting liange, said sheet metal member being applied to said railwith said back or web extending below the bottom face of said rail fromthe inner vertical face thereof andvk with said flange extending beneathand spacedverticallyr below the bottom facer ofl saidy rail, a flexibleflat weather-strip below thebottomface of said rail and having. itsinner marginal portion overlapped bysaid flange; the remainingportion-of said weather-strip projecting outward from said flange andterminating short of. the outer edgeof said rail.; all `portions ofsaid,weather-stripbeing entirely below the bottomA face of. said rail,`andsaidl weatherstrip and said:A flange seating on. the sill, when thesash is closed, and forming the support for said sash,y and fasteningmembers inserted through said flange and the portion of theweather-strip overlapped thereby, for securing said sheet metal memberVand weather-strip to said rail.

In. testimony whereof I have hereunto subscribed my name in the presenceof two witnesses.
